INTRODUCTION

This article describes the hotfixes and the updates that we recommend that you install on each node of a Microsoft Windows Server 2003 Service Pack 2 (SP2)-based server cluster. When you update a Windows Server 2003 SP2-based server cluster, you help reduce downtime. You also help decrease the number of support issues that you experience.

Note We recommend that you evaluate these hotfixes and updates to determine whether they resolve problems in your environment. If you verify that cluster nodes in your environment are affected by the problems that an update or a hotfix addresses, install the hotfix or the update on each cluster node in your environment.

A short summary is included with each hotfix and with each update that appears in the "More Information" section. This summary does not replace the information that is contained in the original Microsoft Knowledge Base (KB) article for that particular hotfix or update. Use this summary information to help you determine whether a particular hotfix or update applies to the server cluster in question. Before you install a hotfix or an update, we recommend that you review the original KB article that describes that hotfix or that update.
